#call this code direction from the web with:

#bash <(wget -O - https://raw.githubusercontent.com/PowerShell/PowerShell/master/tools/installpsh-gentoo.sh) ARGUMENTS

#bash <(curl -s https://raw.githubusercontent.com/PowerShell/PowerShell/master/tools/installpsh-gentoo.sh) <ARGUMENTS>

#Usage - if you do not have the ability to run scripts directly from the web,

# pull all files in this repo folder and execute, this script

# automatically prefers local copies of sub-scripts

#Completely automated install requires a root account or sudo with a password requirement

#Switches

# -skip-sudo-check - use sudo without verifying its availability (hard to accurately do on some distros)

# -preview - installs the latest preview release of PowerShell side-by-side with any existing production releases

#gitrepo paths are overrideable to run from your own fork or branch for testing or private distribution
